Norwegian referee a familiar face to Arsenal

Arsene Wenger may want the referee for Tuesday's game to stay on alert for "tricks" at the Allianz Arena but Svein Oddvar Moen is no stranger to the Champions League level or the team's who will be battling for a place in the quarter-finals.

In fact, he should already be familiar to Arsenal fans, having taken charge of the first leg of their last-16 tie against Bayern Munich last season at Emirates Stadium. He even incorrectly awarded a corner to the home side, a mistake which led to their only goal in a 3-1 defeat.

Moen, an ambulance driver outside the game and the only Norwegian official on UEFA's elite list, has already taken charge of Manchester United's victory at Bayer Leverkusen and Chelsea's win over Schalke this season, too.

And he is one of the seemingly many people who has been involved in an argument with Mario Balotelli: he harshly dismissed the striker during an Italy World Cup qualifier last season, prompting Balotelli to punch a wall in frustration.
